Wearable device and method for changing background object on basis of size or number of foreground objects

Abstract

A processor, comprising processing circuitry, of a wearable device, individually and/or collectively, may be configured to cause the wearable device to: display, on a display, a foreground object superimposed on a background object having a first brightness; based on identifying that at least a portion of the display occupied by the foreground object has increased in size, at least one processor may be configured to change the brightness of the background object to a second brightness that is lower than the first brightness. The disclosure may relate to a metaverse service for strengthening interconnectivity between a real object and a virtual object. For example, the metaverse service may be provided through a network based on fifth generation (5G) and/or sixth generation (6G).
